The ultimate feeling of comfort

NEXUS M EVI heat pumps enable optimal room temperature with minimal energy consumption. They allow the right air temperature to be achieved while simultaneously providing access to hot water to fully meet consumer needs.

Advantages of monoblock construction

The pump is designed entirely for outdoor installation. A key feature of the pump is that the entire cooling system is housed in a single unit, with only the pipes supplying heat to the building extending outside.

Working under extreme conditions

NEXUS heat pumps are innovative system solutions from SUNEX that keep your home warm even at extremely low temperatures down to -25 degrees Celsius. In operation, they offer exceptional efficiency, reliability, and cost-effectiveness.
